Plant microclimate control
Jelínek, Jan ; Neděla, René (advisor) ; Papežová, Stanislava (referee)
This bachelor thesis discusses the management of a microclimate environment inside an
enclosed box. The aim of the work is to propose and implement a program for the
automized control of the microclimate. Microclimate management is ensured by a PLC
(Programmable Logic Controller) system utilizing the program Mosaic. Radishes
(Raphanous sativus L.) were chosen as the test plant. Optimal microclimate conditions for
the chosen test plant were achieved by programming the management system. The system
is easily adaptable, meaning endless different species of plants can be grown properly.
Healthy plant growth indicates the correct parameters of the microclimate.

The Financial Analysis of selected agriculture- food enterprice
Jelínek, Jan ; Hálová, Pavlína (advisor) ; Mach, Jiří (referee)
The bachelor thesis is focused on financial analysis of selected enterprise. The work has been divided into a theoretical and a practical part. The theoretical part describes the concepts for the correct understanding of the financial analysis. There are also described the various pointers used in analysis of company itself.
For a practical part, the company Oseva Agri Chrudim has been selected for analysis. Years 2010 - 2014 have been chosen as rated period. In this part, the company is characterized here and there are used individual methods in practice. The first method is horizontal and vertical analysis of balance sheet and income statement,followed by ratio analysis, bankruptcy models and finally, intercompany comparison.
In the end of the work, the financial situation is evaluated and are given recommendations for future development.

Nonlinear buckling analysis of a flue gas pipe
Jelínek, Jan ; Vincour, Dušan (referee) ; Létal, Tomáš (advisor)
This thesis deals with the nonlinear analysis of stability loss of flue gas pipe. This pipe is a part of desulphurization line. The thesis describes the creating of a simplified FEM model. It also describes the setting of the boundary conditions of the model for few loading cases. These cases differ by preference for one of the load as dominant. There are proposed several variants of stiffening by light ring stiffener. The work is finished by comparing the resistance to the stability loss of the reinforced variants and unreinforced model of flue gas pipe.

Analysis of the mechanical properties of plastic materials for 3D printing
Jelínek, Jan ; Bártková, Denisa (referee) ; Koutný, Daniel (advisor)
This work will solve the mechanical properties of materials used in the FDM technology.Thetensile and flexuralmechanical properties depending on theprintingparameterswillbetested. Fortestingare used three types of sampleswithdifferentrastersforeachof the tests. The first type of raster is characterized by a fundamentalparameter, whichisoffered by themanufacturer. The second type of raster is characterized by a high number of thin-fiber material and a higherconcentrationof air gaps. The third type of rasterischaracterized by minimalnumberof air gaps and a minimum number of thick-fibers in thecross-sectionalofsample. These typesofsamples will be tested on selected materials. The results of individual tests willbecomparedamongselectedmaterials and types of samples. The aim of this work is to show the dependence of mechanical properties on the type ofprintingstrategy.
